They are signaled between PE devices using MP-BGP.

They are swapped at each P router as a packet crosses the service provider network.

They are also known as the inner label or service label.

They indicate to the egress PE the VPRN to which a packet belongs.

The frame is dropped.

The VLAN tag is removed, and the frame is transported over the network.

The VLAN tag is kept, and the frame is transported over the network.

The VLAN tag is kept, a VLAN of 0 is added, and the frame is transported over the network.

A PE uses the same VRF table for all the VPRN services on it.

A PE uses a VRF to maintain forwarding information.

Information for VRFs can be advertised between PEs by MP-BGP.

A PE uses a VRF to route traffic to CEs.

Service tunnels are unidirectional.

Transport tunnels are unidirectional.

A service will use the same service label for every hop.

A local service requires a transport tunnel.

ADSPEC sets an SDP's MTU to the smallest MTU value found along the LSP path.

RSVP must be enabled on all MPLS routers of a path to use ADSPEC.

ADSPEC can automatically adjust the service MTU.

ADSPEC can be enabled on individual LSPs.

The service is a local service.

The service requires a second spoke SDP on this router.

The service's VC ID is 44.

The service will accept VLAN tag 100.

All routes in the VRF are advertised to the PEs and CEs.

No routes in the VRF are advertised to the PEs or to the CEs.

All routes in the VRF are advertised to the PEs, but not to the CEs.

All routes in the VRF are advertised to the CEs, but not to the PEs.

A mirror source with a defined source type.

A mirror source defined with an SDP destination.

A mirror destination with a SAP defined.

A mirror destination and a mirror source with the same service ID.

Service providers can apply QoS, ingress/egress traffic shaping and policing on a per service basis.

Different customers with overlapping address space can be accommodated.

There is a clear demarcation of customer and service provider networks.

Customers can connect to the same service using different subnets.

The labels are of local significance only, so other routers can use the same value.

10.10.10.1 has yet to send its own unique label.

Router R4 is using the same tunnel to send and receive to 10.10.10.1.

The service on 10.10.10.1 is down, so it is rejecting packets.

They are used to identify the VRF table for a prefix at the receiving PE.

They are used by VPRNs to control the distribution of VPN routing information.

They are distributed to all PEs and CEs that are part of the VPRN.

They are distributed to PEs to identify the VRF table that a VPN-IPv4 prefix is associated with.

By default, a VPLS signals an MTU based on the network port.

By default, an IES sets its ip-mtu to the VC MTU of the VPLS.

By default, an IES uses an MTU value based on its SAP.

By default, an IES uses an MTU based on the network port.

Each router requires 1 SDP.

Each router requires 2 SDPs.

Each router requires 3 SDPs.

Each router requires 6 SDPs.

VPRN is an IP service that connects multiple sites in a single routed domain over the provider-managed IP/MPLS network.

Each VPRN consists of a set of customer sites that must connect to the same PE router

In a VPRN service, each customer router becomes a routing peer to other customer routers

VPRN provides customer routers with transparent IP connectivity without knowledge of the MPLS core

6VPE is a tunneling technology that makes use of MPLS tunnels to transport IPv6 information over an IPv4 MPLS infrastructure.

Customers connected to 6VPE could run native IPv6 or IPv4.

On the PE router, the next hop for a VPN IPv6 address is an IPv6 address, regardless of the nature of the network between the PEs.

6VPE requires an IPv6-aware MPLS core.

Both C and D are false.

All of the above statements are true.

A mirror source listing port 1/1/4.

A mirror destination listing port 1/1/4.

A remote source command indicating the IP address of the service router he is configuring a local mirror on.

An SDP can be used by more than one service and customer.

A SAP can only be created on an access port.

A customer can have multiple services associated to it.

A customer is only created on one site of a distributed service.

Mirror slicing is used to logically separate a port that is being monitored.

Mirror slicing configuration is earned out in the mirror destination.

By default, mirror slicing is enabled so that only the protocol headers of data traffic are replicated to a mirror port.

The maximum number of mirror slices that can be made on a network and access port are 256 and 8, respectively
